Application filed September 20, 1917. Serial No. 192,270.

To aZZ 'whom t may cof/wem.'

Be it known that I, BERGET H. BLooKsoM, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Refrigerators, of which the followin is a specification.

rlhis invention reates to refrigerators and more particularly to insulation therefor, the object of my invention being to provide a more economical and efficient heat insulation whereby the cooling medium of the refrigerator is conserved.

Further objects and advantages of my invention will be apparent as it is better understood by reference to the following specification when read in connectlon with the accompanying drawing, illustrating the preferred embodiment thereof, in vvhlch- Figure 1 is a transverse section through a refrigerator illustrating the apphcation of my invention and Fig. 2 is a view in sulating material.

To illustrate my invention I have shown in the drawing an ordinary refrigerator adapted for household use but 1 t 1s to be understood 'that my invention hasva much Wider application and may be employed in large refrigerators such as are used in stores and packing houses and in refrigerator cars. The material may be employed in fact with all constructions where an efficient heat insulating material is desired.

Referring to the drawing 5 indicates the outer shell of the refrigerator which in the present embodiment is constructed of tWo layers of Woodland is supported on a suitable base 6. In the corners of the shell I provide spacing members 7 to support an intermediate shell8 also preferably of Wood in spaced relation to the outer shell 5, thus leaving an air space 9. In the corners of the intermediate shell 8 I provide spacers 10 to support an inner shell 11 in spaced relation to the intermediate shell 8. The refrigerator may have a metal lining 12 within the inner shell 11. Doors 13 and 14: are mounted in the front of the refrigerator to close suitable openings giving access to the interior thereof. kThe doors preferably correspond in construction to the remainder of the shell.

perspective of the in- In Fig. 2 of the drawing I have illustrated a section of a curled hair bat which serves as the insulator for the refrigerator above described. The bat .is formed by providing a layer l5 of curled hair and .securmg a relnforcing fabric 16, such for eX- ample as burlap to one face of the layer by forcing portions of the hair through the interstices of the fabric as indicated at 17 in ig. 2.

Again referring to Fig. 1 it will be seen that a layer 1.8 of the reinforced curled hair material 1s dlsposedbetween the intermediate and inner shells 8 and 11 and 'between the corresponding portions of the doors 13 and 14:. The chamber of the refrigerator is thus completely surrounded with insulat- 1n material, I

have dlscovered that the reinforced curled hair material desc1ibed,herein constitutes a very superior insulating material for refrlgerators of all kinds and that 1t 1s extremely eiiicient in the conservation of the cooling medium. The material'is relatively ineXpensive and is easil applied in manufacturing refrigerators. efrigerators which will successfully maintain very low temperatures may be thus constructed at a cost whlch permits commercial -manufacture and sale thereof.

It will be -apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. In a refrigerator, an outer shell, an intermediate shell, spacer members enveloping each of the corners of said intermediate shell and maintaining said shells in spaced relation to form a dead air chamber therebetween, an inner shell spaced from said intermediate shell, and a layer of curled hair in the space between said inner and said vintermediate shells.

2. In a refrigerator, an outer shell, spacer members ittting in each of the interior corners of said outer shell, an intermediate shell Within said outer shell and maintained in spaced rel-ation thereto by said/spacer members to form a dead air chamber therebetween, spacer members fitting in each of v the interior corners of said" intermediate shell an inner shell within said intermediate shell and maintained in spaced relation thereto by said spacer members, and a layer of reinforced curled hair in the space between said inner and said intermediate shells and surrounding the refrigerator chamber.

3. In a refrigerator, an outer shell, an intermediate shell spa/ced from said outer shell by spacing members at each of the corners to form a dead air chamber be-.-

tween said shells, an inner shell spaced from said intermediate shell, a layer of curled hair between said inner and said inter- 15 mediate shells, and a door giving affess to the refrlgerator chamber having spaced shells and air chamber corresponding to the shells and air chamber of the refrigerator bodyVand a layer of curled hair between 20 ghe lnner and the intermediate shells of said oor.
